As regular readers know, the Treehouse exists simultaneously in the United States and Australia and as such it makes an effort to celebrate astronomical phenomena in both hemispheres and on both sides of the Earth.
Since it’s already Tuesday December 22 in Australia, we’re later for the summer solstice than we are for the winter one (which occurred about 13 hours ago in North America), but we are still at the beginning of summer in the southern reaches and winter in the northern ones and still feel celebratory. So we want to send best wishes to all of our fellow Earthlings (along with our hopes for a much improved New Year).
